Brangelina, TomKat, Garfleck and Ashmi: they might sound like cartoon characters or chocolate bars, but they're all names used to refer to Hollywood supercouples, as you'll no doubt know already - unless you've been living in Siberia for the past year or so, that is (and just in case you have, Vaughniston is no more).

Media and public interest in the super-rich, famous and beautiful, and their equally beautiful offspring, is at an all-time high, and mono-monikers are just one sign that the supercouple is becoming a virtual phenomenon of the society we live in. When magazines are prepared to pay millions of dollars just for the first baby pics of your little Suris and Shilohs, and the paparazzi start setting up camp outside your doorstep, you know you've gone from A-list lovers to fully-fledged supercouple. 

There's something about a celebrity love match that really captures the imagination and brings out the voyeur in us: when rich, famous and successful meets rich, famous and successful, does it equal a passionate relationship based on mutual understanding and respect, or a showcased play-act lived out in front of the cameras? Let's face it, in the plastic world of stardom it's been known for celebs to fake entire relationships with other celebs just for the tabloid space that's in it.

Perhaps what we're really curious about is how our supercouples live their lives off the red carpet and how they retain any semblence of normality while juggling red-carpet events and premieres, splitting their time between mansions around the globe, having kids and saving the world, to mention nothing of work...We thought golden couples Jen and Brad and Ryan and Reese had it all; but really, with the pressures of fame, fortune and living in the 'real' world, is it any wonder so many golden couples don't go the distance?  

Discover the stories behind the supercouples and how they make it work, and tell us which couple you think will stand the ultimate test of time.
